Dickow, Auburn, N.Y., assignor to The Eastern Company, Naugatuck, Conn., a corporation of Connecticut Filed Feb. 28, 1967, Ser. No. 619,451 2 Claims. (Cl. 114--207) ABSTRACT OF THE DISCLOSURE Kedge type anchor having a channel iron stock pivoted on the lower end of the anchor on the shank of a retrieval eye and between the anchor end and an integral diagonal bridge strap which limits the rotation between positions parallel with and at right angles to the anchor fluke arms, the bridge strap having grooves to receive the channel flanges in the two positions, and a spring threaded on the eye shank and bearing against the shank to yieldingly lock the stock in either position.
This invention relates to boat anchors, and more particularly to a kedge type anchor having a shiftable stock.
In anchors of the kedge type a stock extending transversely of the flukes is necessary to cause the anchor to assume a dig in position. The stock is necessarily of substantial length to be effective, and as a result the anchor is cumbersome to store, while not in use.
The present invention is directed to an anchor wherein the stock is shiftable from a position parallel with the flukes for storage to an active position extending transversely of the flukes. The arrangement is such that the stock is readily shiftable from one position to the other manually, and when set'in either position, a lock is effected, to securely hold it in position. More particularly the invention includes a stock which may be of channel iron configuration and which is pivotally mounted at the fluke end of the shank, the pivot mount having a bridging strap acting as straps for the two positions, and providing locking grooves into which the channel flanges are held under spring pressure, when manually set.
The above and other novel features of the invention will appear more fully hereinafter from the following detailed description when taken in conjunction with the accompanyingdrawings. It is expressly understood that the drawings are employed for purposes of illustration only and are not designed as a definition of the limits of the invention, reference being had for this purpose to the appended claims.
In the drawings, wherein like reference characters indicate like parts:
FIGURE 1 is a side view of the anchor, with the stock disposed in storage position;
FIGURE 2 is a sectional view of the anchor taken on the line 22 of FIGURE 1, with the stock turned and disposed in transverse position to cause the anchor flukes to dig in;
FIGURE 3 is a fragmentary sectional view taken on the line 33 of FIGURE 1, with the stock disposed as in FIGURE 2;
FIGURE 4 is an enlarged fragmentary side view of the stock mount;
FIGURES is a fragmentary section taken on line 55 of FIGURE 4, and
FIGURE 6 is a sectional view taken on the line 66 of FIGURE 5 with the stock removed.
Referring to the drawings there is shown an anchor having a shank 20 of I section, with an eye 22 at one end and integral fluke arms 24 and 26 at the other with flukes 25 and 27. Pivotally disposed beneath the arms is a stock 28 in the form of a heavy channel sectional member, pivoted on the stem 30 of an anchor retrieval eye 32, the stem being threaded into a socket 34 in the fluke end of the shank 20.
Bridging the mid portion of the stock, is an integral strap 36 disposed on a diagonal and supported from short columns 38 and 40 connecting the strap 36 with lateral projections 42 and 44 extending oppositely from the web 43 of the fluke arms 24 and 26. The inside face 45 of the inclined strap portion is provided with transverse grooves 46 and 48, and lengthwise grooves 50 and 52 which are adapted to receive the edges 54 and 56 of the channel member flanges 58 and 60. The web portion 62 of the channel sectioned stock is provided with an aperture 64 through which the stem 30 of the eye 32 extends. An annular recess 66 in the end of the shank, around the stem 30, provides space for a heavy coil compression spring 68, which bears upon the web 62 of the stock, and presses the flange edges 54 and 56 into either set of grooves 46 and 48, or 50 and 52, the channel edges being shown as engaging grooves 46 and 48 in FIGURES 2-6, and grooves 50 and 52 in FIGURE 1. The spacing between the inside face 45 of the strap, and the end surface 70 of the shank 20 is a little greater than the thickness of the channel section of the stock. It will be seen that the inside surfaces 72 and 74 of the columns 38 and 40 are parallel and spaced apart by the width of the channel section of the stock, and that the end edges 76 and 78 of the columns 38 and 40 are likewise so spaced as to accommodate the stock in a position at right angles to the surfaces 72 and 74.
The compression of the spring 68 is such as to yieldingly, but securely, hold the stock either crosswise of the flukes, or lengthwise thereof, the spring being preloaded in holding the channel flange edges 54 and 56 in either one set of grooves 46 and 48, or the other set 50 and 52. The stock is disposed with its flanges in grooves 50 and 52 for storage, and is shifted through degrees to place the flange edges in grooves 46 and 48, prior to dropping anchor, the shift being readily effected manually against the pressure of the spring 68, which readily yields for the purpose, but which is heavy enough to securely hold the stock in crosswise position so that the stock will be effective in causing one or the other of the flukes to take a digging in position.
It will be seen that the anchor proper, may be readily formed as a malleable casting, and hot-dipped galvanized if desired, and that the stock, because of its pivotal mount, which permits storage, can be of any length desired, since when not in use it is out of the way. By preloading the spring to a substantial degree, when it is holding the stock in either one of the positions referred to, the spring may be manually compressed without adding greatly to the spring pressure, to permit lifting the flanges out of the grooves to permit the relocation of the stock in the alternate position.
Although single embodiments of the invention have been illustrated and described, it is to be understood that the invention is not limited thereto.
What is claimed is:
1. An anchor comprising a shank having an eye at one end and integral opposite extending arms terminating in flukes at the other, a stock pivotally mounted on the fluke end of the shank for rotation about the axis of the fluke, manually releasable yielding means for securing the stock in a position transverse to the plane of the fluke arms, said fluke arm end of the shank having an integral bridged strap spaced from the said end of the shank and extending at an angle to the fluke arms, and the stock comprising a channel member having spaced flanges and a web extending through the spaced between the shank end and strap, and said stock being pivoted on a retrieval eyebolt 3 4 extending through the strap and an aperture in the stock ingly hold said stock in a position lengthwise of said web, and threaded in the shank end and said bridge strap fluke arms.
